What symptom is associated with epiglottitis?

Stridor is a high-pitched, wheezing sound caused by disrupted airflow, often associated with upper airway obstruction. In the context of epiglottitis, stridor occurs due to inflammation and swelling of the epiglottis, which can partially obstruct the airway. This condition is particularly serious, especially in children, as it can lead to respiratory distress if the swelling progresses. Stridor often signifies that immediate medical intervention is necessary to secure the airway and manage the underlying inflammation. In contrast, rash, diarrhea, and jaundice are symptoms associated with other conditions and do not specifically indicate epiglottitis, making stridor the most relevant symptom in this scenario.
